STS-100 static transfer switch(STS)
The STS dual-input AC converter switch is a paragon of intelligent
power management. Integrated with advanced control systems, it
continuously monitors the status of both AC inputs, collecting data
on parameters like voltage, current, and frequency. Using this real
- time information, the STS can proactively predict potential power
issues and initiate preventive switching actions. For example, if
it detects a gradual degradation in the quality of the primary
power source, it can switch to the secondary source before a
failure occurs. This intelligent management not only ensures
uninterrupted power supply but also provides valuable insights for
power system optimization and maintenance, making it a high - tech
solution for modern power distribution networks

FAQ :
1. How do you ensure product quality?
Rest assured, our products undergo three rigorous tests before
leaving the factory. First, we simulate real - world usage
scenarios to assess their actual performance. Then, we conduct no -
load and full - load stress tests to verify stability under extreme
conditions. Finally, the current sharing test is carried out to
ensure zero errors when multiple devices operate in tandem. For
instance, the equipment we supplied to a large - scale data center
achieved 365 consecutive days of trouble - free operation thanks to
this comprehensive testing process.
2. What is the minimum order quantity?
Whether you need 1 unit or 10,000 units, we've got you covered! We
accept orders starting from a single unit, and production and
delivery can be arranged within 3 working days. For bulk purchases,
you'll enjoy tiered discount prices and priority production
scheduling. Just last month, a startup customer ordered 5 sample
units for testing. After they were satisfied, they placed a follow
- up order of 500 units, and the whole process was seamless.
It’s our pleasure to present a comprehensive overview! We’ll share
a dynamic visual corporate brochure (including our development timeline, R&D team, production
capacity layout, and client cases) to showcase our credentials. The
document will be sent to your contact email shortly for the most
direct insight into our business landscape.
